The first method under consideration is the waterfall development method (Melonfire‚ 2006). Waterfall development is a software development model‚ which comprises of a phased succession of actions leading to the delivery of a software product. In essence‚ it is a framework for software development in‚ which development continues successively through

process of developing an information system. There are many different methods that Smith Consulting can look into. One of the more popular methods is the waterfall method. Based on the idea that you only move forward in a project. The steps are sequential and must be completed before moving to the next one. There are many variations of waterfall method. Most of them follow something close to the following steps: Conception or Requirements Design

(Endre & Rombach‚ 2003) Requirements are the basic Phase which lead to the development of a project. In fact‚ it is the first step for any project The main problem in a project failure is the lack of requirements. The common requirement error is due to human (i.e lack of Communication between customer and the analyst)‚ software‚ etc.

to structure‚ plan‚ and control the process of developing an information system. Here are some iterative methodologies that can be used especially for large projects and some of their characteristics. Spiral Model The idea is evolutionary development‚ using the waterfall model for each step; it’s intended to help manage risks. Don’t define in detail the entire system at first. The developers should only define the highest priority features. Define and implement those‚ then get feedback

circumstances would RAD be used and why? RAD would be used when the programme would be under a heavy time constraint‚ therefore needs to be completed quickly. What is Prototyping and in what ways is it used in RAD? Prototyping is an early sample or model of a programme in the purpose to test its uses and to test its usability. Prototypes are often learned from when producing future programmes. In RAD prototypes are produced before the final programme to see if it meets the requirements. Prototypes
